Fixed a typo in the console text in main.c.
Translated the doc of BbQueue as this project is supposed to be internationalizable (and therefore documented in English).
Also fixed the disorganized backslashes cloud of #define statements and re-aligned function arguments properly.
Translated small comments in BbQueue.c for the reasons mentionned in 908d7cb35aa02cd9ed9cc467756dff69d2f7004f
More translation as well as extremely minor indentation fixes.
Modified possibly misleading terms used throughout the code. (such as Class or Methods)
